Application filed. October 2, 1924. Serial No. 741,155.

The invention relates to printing presses,

and more particularly to reversible driving.

mechanism for rotary web presses.

Objects and advantages of the invention 5 will be set forth in parthereinafter and in part will be obvious herefrom, or may be learned bypractice with the invention, the same being realized and attained bymeans of the instrumentalitie and combinai tions pointed out in theappended claims.

The invention consists in the novel parts, constructions, arrangements,combinations and improvements herein shown and described.

The accompanying drawings referred to herein and constituting a parthereof, illustrate one embodiment of the invention, and together withthe description, serve to explain the principles of the invention.

Fig. 5 is a fragmentary section and bottom plan, taken on the line 55 ofFig. 4.

The invention is directed to improvements in fast rotary web presses ofthe newspaper or magazine class, whereby a large variety of products maybe secured from a press 0t a given construction, including multi-coloredproducts, such as the colored magazines and comic sections ofnewspapers. The present invention is directed primarily to novel drivingmechanism for the various printing couples, each printing couple beingindividual ly driven from a common driving shaft, vertically disposed attheside' of the press, the general arrangement of such a drivingmechanism being shown and described in Patents 700,100 and No. 700,101to GOSS, dated A 19. 1902.

ly shown and described in Patent No.

528,233 to Michaud dated October 30, 1894. The broad idea of independentreversible gearing or drive for a press of this type is shown anddescribed in Patent Number 555,460 to Michaud, dated Feb; 25, 1896.

. While the present invention is examplarilydisclosed applied to a pressof the general Michaud type, and to a verticall disposed shaft drive ofthe type shown in the Gross patents mentioned, the novel features of myreversible drive mechanism are equally applicable to other general typesof presses, and in its more important feature it is to a great degreeindependent of the type of press in which it may be incorporated andused.

In the present preferred embodiment,

broadly considered, the printing couples are arranged invertically-disposed series or rows, at either side of an 0 en space, on

which space the impression cy inder of each printing couple faces. Adriving shaft for all the printing couples of a vertical series isvertically disposed at one side or end of the series of printingcouples, but without being in any essential relation to either the formcylinders '01- impression cylinders of the various printing couples.There are'reversible driving mechanisms between this shaft and each ofthe printing couples, the entire reversible driving mechanism beingpreferably on one side of the respective printing couples, without anyconnections or mehanism extending across the press, and preferably alsothis reversible driving mechanism is entirely outside of the side frameof the press. p

Meshing with a single continuously rotating bevel gear, which is infixed position on the vertical shaft, is a likewise con-- tinuouslyrotating combination gear, comprising a driven bevel gear meshing withaccompanying drawings,

i o erative relation at the left hand of Fig. 1.-

direction of rotation selected for the firstanentioned bevel gear and aspur gear fixed to the driven bevel gear and 1'0 tating therewith.liixed to the respective shafts of the form cylinder and impressioncylinder of each printing couple, and preferably on extensions of theseshafts outside the press side frame, are broadfaced slip gear wheels.These two gears rotate with the respective shafts of the form andimpressioncylinders of the printing couple, and are continuously in meshwith each other, but may be alternatively slipped out of mesh with thespur gear of the combination gear just described.

The selective and alternative slipping of these two gears into and outof mesh with the spur gear of the driving combination gear wheelconstitutes means for driving the printing couple selectively in eitherdirection. The two cylinders of the printing couple are caused to rotatein. unison by reason of the continuous meshing of the.

broad-faced slip gears mounted on the cylinder shafts.

It will be understood that the foregoing general description of thepresent preferred embodiment of the invention, and likewise thefollowing full detailed description, is

illustrative and explanatory only, but is not pendent upon the number ofwebs, the ar-' rangement thereof in the press, and the differentprinting couples.

The source of web supply is not shown, but a plurality of web rolls areusually in hese sources .of web supply will be adequate in number andmay be of any known or suitable form so far as concerns the mainfeatures of the present invention.

A pluralit of printing couples are arranged one a ove another, and areshown as four in number, the first couple comprising impression cylinlerand form cylinder 2, the second including impression cylinder 3 and formcylinder 4, the third having impression cylinder 5 and form cylinder 6,and the fourth having impression cylinder 7 andform cylinder 8. Theinking mechanism for the first printing coupe is indicateddiagrammatically by 9, that of the second printing couple by 10, thatfor the third printing couple by 11 and that for the fourth by 12.

These inking mechanisms are preferably of the usual type, which ismounted on a carriage movable to and fro on the machine frame fromoperative position with respect to the form or plate cylinder, to aretracted position leaving space for the plates to be changed on theform cylinder and for the inking mechanism to be cleaned, replenished orotherwise attended to.' The inking mechfrom in the press to leave roomfor the passage of a workman between the two series, and has theimpression or blanket cylinders facing on this open space as disclosedin the Michaud patentsalready referred to. The first printing couple inthis secondseries comprises an impression cylinder 20 and a formcylinder 21, the second couple com ris in an impression cylinder 22 anda orm cy inder 23, the third couple comprising an impression cylinder 24and a form cylinder 25 and the fourth couple com. rising an impressioncylinder 26 and a orm cylinder 27 The respective inking mechanisms arerepresented dia rammatically at 28, 29, 30 and 31, each of these beingshown in the operative position with respect to its form or platecylinder.

The general frame structure of the ress comprises a plurality ofF-shaped mem rs, each member being two decks high, and having each anupright member 32v and two cross members 33 and 34. The two membersconstitutin a frame unit are righthanded and left-handed with respect toeach other, and their cross reaches 33 and 34 are bolted together at 35and 36. A similar construction and arrangement may be used and is shownfor each pair of printing couples and each pair of dec A plurality ofbracing or cross pieces 37 may be employed between the di erent pressunits.

Any suitable folding mechanisms may be employed, as may be foundadvisable or de sirable with the particular type or construction ofpress wherein the invention is embodied, and in the drawings, a pair oflongitudinally disposed single formers 39 and 40 are shown withcooperating cross-folders 41 and 42. It will be understood, however,that these-may be selected and varied as desired. A slitter 43 forcentrally or other wise slitting the web is shown diagrammatically, aturner bar or system of turner bars 44 being also similarly shown. 1

Referring now more particularly to the details of the press drive. adriving shaft 54 is shown arranged longitudinally beneath and alongsidethe press, and this maybe provided with any usual or suitable throwoutclutchfreversible gearing drive, or any other Fixed on shaft 54 is a.bevel gear wheel 55, which meshes with a bevel gear wheel 56,

fixed on a vertically-disposed driving shaft 57. This shaft hasindividual driving connection with each printing couple, but is not inany essential relation to the shaft of either the impression cylinders01' the plate cylinders, as the shaft does not drive direct- 1y onto thecylinders 'of the printing couples, but the direction-reversing gearingis interposed between the gear wheels on this shaft and the cylinders ofthe printing couple. Shaft 57 is supported in bearings 58, 59, 60. 61and 62, carried on the side frame of the press, and has fixed theretosingle bevel gears 63, 64, and 66, one for each printing couple.

There is a reversible drive for each of the printing couples from thebeveled gears 63. 64:, 65 and 66, and the description of one of thesereversible driving mechanisms will sufiice for all of them.

Meshing with one of the bevel gears, say car 63 (Figs. 3, 4 and 5), is abevel gear 6 mounted to rotate freely upon a shaft 77,

which shaft is fixed within and supported by a bearing 78, integral withand extending outwardly from the side frames 79 of the press. This shaftis held in position by any suitable means, and as shown, a washer 80 ison the inside end of shaft 77, and a retaining nut 81 is threaded on theend of the shaft, the washer and nut bearing on a boss 82 on the insideof the press frame. A spur gear wheel 86 is fixed to rotate with thebevel gear wheel 7 6, and as embodied these two constitute a combinationdriving gear. As shown. this spur gear wheel 86 is mounted to rotatefreely on the shaft 77, and the bevel gear wheel 76 is fixed to the sideface thereof by screw bolts 87 and 88. Thus the combination gear wheelrotates continuously with the bevel gear wheel 63 on shaft 57.

In the particular printing couple, the inipression cylinder 89 has oneend of its shaft 90 journaled in a. bearing 91 inthe side frame of thepress, the shaft extending yond the bearing and exteriorly from the sideframe. A broad-faced spur-gear wheel 92 is mounted on the shaft 90 torotate with but to slide along the shaft. For this purpose shaft 90 isprovided with a spline or feather 93, and a clamping screw 94 in the hub95 of the gear wheel serves to hold the gear wheel 92 in the desiredposition. A washer 96 and a nut 97, screw-threaded on desired orconvenient connection.

the end of the shaft, retain the gear wheel on the shaft.

The form cylinder 99 cooperates with the impression cylinder 89, and oneend of its shaft 100 is journaled at 101 in the press side frame, theshaft 100 likewise extending exteriorly beyond the bearing and sideframe. A broad-faced spur-gear wheel 102 is mounted upon this exteriorend of the shaft 100, to rotate therewith but to slide therealongf Gearwheel 102 is mounted on shaft 100 by means of a spline or feather 103,and a clamping screw 104 in the hub 105 of the gear Wheel serves to holdthe gear wheel in either desired position. A washer 106 is held in placeby nut 107 screwthreaded on the end of the shaft 100 to keep the gearWheel on the shaft. This slip gear wheel 102 is continuously in-meshwith the slip gear wheel 92 on the shaft of the other cylinder, but theyare relatively slidable while so intermeshing.

The spur gear 86 of the combination gear is continuously driven in onedirection through the bevel gear 63 on the shaft 57 driving the bevelgear 76 of the combination. In Fig. 3, spur gear 102 is slipped out tothe exterior position on the shaft 100 whereby it is in mesh with spurgear 86 of said combination gear. Due to theinbroad faces, gear wheels102'and 92 are always in mesh with each other, and in this position,gear wheel 92 is driven from gear wheel 102, and the cylinders 88 and 99are rotated together in a desired direction.

In Fig. 5 the-reverse relation of the driving gears is shown, as in thisfigure gear wheel 92 has been slipped into mesh with the spur gear wheel86 of the combination gear, and gear wheel 102 has been slipped out ofmeshwith spur gear wheel 86, but the two broadfaced gear wheels 92 and102,

it will be recalled, are continuously in mesh.

The combination gear wheel is now driving to gear wheel. 92 in theopposite direction from that in which it drove gear wheel 102, thusrotating the printing couple in the opposite direction. The gearwheels'92 and 102 being in mesh, the form cylinder and impressioncylinder are now rotated together in the opposite direction.

From all the foregoing it will be understood that a mechanism has beenprovided constituting an exemplary embodiment of the invention, andrealizing the objects and advantages herein set forth, together withother objects and advantages. llt will be understood further thatdepartures may be made from the exact mechanism as shown and described,within the scope of the ac companying claims, without departing from theprinciples of the invention and without sacrificing its chiefadvantages.
